A global software company distributes large installation packages from an Amazon S3 bucket. During release week, many users in the same region download the same file repeatedly, and the origin bill is rising because the same objects are fetched over and over. The team wants to lower origin data transfer and improve delivery cost. Which two actions should it take? Select two.
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Put Amazon CloudFront in front of the S3 origin.
CloudFront caches popular package files at edge locations, so repeated downloads can be served without repeatedly hitting S3. That reduces origin data transfer and improves user download performance, which is exactly what this scenario needs.
B
Best answer
Use versioned object names and long cache TTLs for the release artifacts.
Versioned filenames make it safe to cache the packages aggressively because a new release uses new object names. Long TTLs then let CloudFront reuse cached copies for many downloads, cutting origin requests and lowering cost.
C
Distractor review
Disable caching so every user always gets the newest file from S3.
Disabling caching guarantees more origin traffic, higher latency, and higher S3 data transfer costs. The files are release artifacts, so they are well suited to aggressive caching with versioned names.
D
Distractor review
Serve the downloads from a self-managed EC2 web server instead of S3.
A self-managed web server adds patching, scaling, and availability work and does not automatically reduce data transfer cost. It is usually more expensive than serving static packages from S3 through CloudFront.
E
Distractor review
Move the release packages to S3 Glacier Deep Archive for faster downloads.
Deep Archive is for extremely low-cost long-term retention, not for active software distribution. Retrieval is slower and more expensive than standard storage classes, so it is the wrong fit for frequently downloaded packages.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this SAA-C03 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Put Amazon CloudFront in front of the S3 origin. — CloudFront is the right way to reduce repeated S3 origin fetches for large downloadable files, especially when many users in a region request the same artifact. Versioned object names let you cache safely for long periods because each release has its own filename, so you do not need to invalidate frequently. Together, these changes reduce origin traffic, improve delivery speed, and lower overall transfer cost. Disabling caching guarantees more origin traffic and higher cost. A self-managed EC2 server increases operational burden and does not inherently save transfer charges. Glacier Deep Archive is for archival, not active distribution. The correct answer combines CDN caching with immutable release artifacts, which is the standard cost-optimized pattern for software downloads.
